Geographic population health information system

ABSTRACT

A method and system for providing a data analysis in the form of a customized geographic visualization on a graphical user interface (GUI) on a remote client computing device using only a web browser on the remote client device. The system receives a user&#39;s selected data analysis to be performed by the system for display on the remote client device. The system verifies the data access permissions of the user to render a data analysis solution customized to that particular user, and automatically prevents that user from gaining access to data analysis solutions to which that user is prohibited. The system is configured to respond to the user&#39;s data analysis request, perform the necessary computations on the server side on the fly, and send a dataset interpretable by the client device&#39;s web browser for display on the client device or on a device associated with the client device.

BACKGROUND

This application relates generally to the field of healthcare data analysis, and more specifically to systems and methods for displaying geographic population health information.

Existing systems for analyzing population healthcare data based on population distribution, disease state, and access to options to improve health requires software residing on the user's computing device or system to store, compute, manipulate, integrate multiple data sources, and display the results of massive datasets. Most likely, such software residing on the user's computing device or system includes database management software to perform data management functions. As new datasets are made available, software on the user's computing device or system requires updates to enable access to the new datasets as such software updates are released. In addition, to render a spatial distribution on a user's computing device or system, existing methods and systems require software on the user's computing device or system to facilitate integration of the disparate data assets with geographical information system software to produce a composite rendering on the graphical user interface.

The proposed software and associated system of the instant disclosure addresses these and other limitations of existing systems by using a client device's web browser to display geographical population health information data that the system collects, assembles, and preformats from disparate data sources for on-demand, dynamic, interactive display in the web browser.

DETAILED DESCRIPTION

Although the figures and the instant disclosure describe one or more embodiments, one of ordinary skill in the art would appreciate that the teachings of the instant disclosure would not be limited to these embodiments. Various embodiments of the instant disclosure relate to integrating, analyzing, and visualizing geographic, population-based, health data on computer displays associated with one or more remote client computing devices without requiring client-side software on the client device other than a web browser. The system herein disclosed eliminates the need for enterprise-wide software installations on client devices, and of the need to modify client-side computing devices to access the requested data. The system herein disclosed also avoids data capacity limitations that would prevent the client computing device from rendering the requested topographical data. The system provides users with on-demand, user customized data analysis through a server system that may include a cloud-based server system.

Turning now to the drawings wherein like reference numerals refer to like elements, FIG. 1 shows an illustration of one embodiment of a system architecture that solves the problems associated with existing systems. In this embodiment, system 10 includes server system 110 hosting application software that responds to requests from client system 100.

Server system 110 may include any web server such as a cloud-based server or a dedicated server system. Server system 110 in this embodiment includes various hardware and software elements, including map server 111, custom geographic data selection manager 112, community health management (CHM) web server 116, user security tabular data assessor 117, and custom data selection manager 120. Referring to FIG. 3 , custom geographic data selection manager 112 may also include map identifier 113 and layer identifier 114. Referring to FIG. 4 , user security tabular data assessor 117 may include group security identifier 118 and tabular layer identifier 119.

Server system 110 in this embodiment also includes connections to various databases, including geo-spatial database 115, claims database 121, nutrition database 122, physical fitness database 123, and social determinants of health database 124. One of ordinary skill would appreciate that in other embodiments, server system 110 may implement multiple other servers and databases or fewer than what is shown in FIG. 1 . Server system 110 may also include one or more computer processors, one or more data memory storage elements, one or more input/output buses and data ports to enable the communication of data to and from server system 110 via one or more wired, wireless, wifi, cellular, and satellite networks via the Internet, the world wide web, or any other communications protocol.

Geo-spatial database 115 may include and store a plurality of shapefiles. Each shapefile may include one or more points or vertices, one or more lines connecting at least two vertices, and/or one or more polygons connecting at least three vertices. Geo-spatial database 115 may include and store at least one shapefile including a plurality of polygons, each corresponding to a respective zip code. Claims database 121 may include geolocation data, organization data, and bar code scan data files. Nutrition database 122 may include healthcare administrative claims data. Physical fitness database 123 may include geological data and image data of impervious surfaces. Social determinants of health database 124 may include alphanumeric descriptive data.

Client system 100 may include graphical user interface (GUI) 101, such as a display, and Internet web browser 102, such as Internet Explorer, Safari, Firefox, or Google Chrome, to name a few. Client system 100 may also include client ID 108 representing a unique identifier that may be registered with server system 110 so that server system 110 recognizes and returns requested data back to the same client device. Referring to FIG. 2 , web browser 102 of client system 100 may include dynamic display 103 including graphical image viewer 104, and web page renderer 105 including image converter 106 and graphical composite assembler 107.

In one embodiment, map server 111 authenticates client ID 108 after receiving a service token from web browser 102. The custom geographic data selection manager 112 receives the client input/selection (i.e. query) for a layer and retrieves, via layer identifier 114, one or more shapefiles (or portions thereof) from geo-spatial database 115. The one or more shapefiles (or portions thereof) retrieved from the geo-spatial database 115 may be referred to as the appropriate shapefiles. To retrieve the appropriate shapefiles, map identifier 113 of custom geographic data selection manager 112 uses a map identification routine to select the requested map, and layer identifier 114 of geographic data selection manager 112 selects the appropriate layers from the selected map. The layers from the selected map include vertices files that are combined to form the shapefile. The selected shapefile is sent to the map server 111 as a response to the original request from the web browser 102.

The custom data selection manager 112 may further retrieve, via map identifier 113, one or more reference shapefiles from an external database. The one or more reference shapefiles may be used to build an underlying reference map upon which the appropriate shapefiles are overlaid.

To retrieve the appropriate shapefiles and/or the reference shapefiles, layer identifier 114 and/or map identifier 113 of custom geographic data selection manager 112 may determine outer coordinates of a displayed portion of the reference map. For example, the displayed portion of the reference map in FIG. 7 is almost the entire United States and small portions of the Pacific and Atlantic Oceans, whereas the displayed portion of the reference map in FIG. 8 is Chicago. According to one embodiment, map identifier 113 retrieves the reference shapefiles from the external server before the layer identifier 114 retrieves the appropriate shapefiles from the geo-spatial database 115.

To determine the outer coordinates layer identifier 114 may determine (a) a zoom level of a reference map currently displayed on GUI 101 and (b) a center of the reference map currently displayed on GUI 101. Layer identifier 114 may learn the zoom level of the reference map by querying the client system 100. Alternatively, layer identifier 114 may have previously learned the zoom level of the reference map in order to retrieve appropriate reference shapefiles of the reference map. Based on the zoom level and the center of the reference map, layer identifier 114 may determine outer coordinates of a displayed portion of the reference map. Alternatively or in addition, layer identifier 114 may determine the outer coordinates of the displayed portion of the reference map by determining outer-most vertices, lines, or polygons of reference shapefiles being used to render the displayed portion of the reference map.

Layer identifier 114 may determine which sets of shapefiles stored in the geo-spatial database 115 include the appropriate shapefiles based on a user selection of one or more layers on a drop-down menu displayed on GUI 101. For example, the geo-spatial database 115 may include (a) one set of one or more shapefiles representing zip codes of the United States, (b) one set of one or more shapefiles representing state lines of the United States, (c) one set of one or more shape files representing city boundaries of the United States. Layer identifier 114 may only retrieve shapefiles from the applicable sets of shapefiles. For example, if the user-selected layer is segmented according to zip code, but not according to city boundaries, then the layer identifier 114 may only retrieve shapefiles from sets (a) and/or (b), but not from set (c).

It should thus be appreciated that layer identifier 114 may determine the applicable sets of shapefiles of geo-spatial database 115 and that layer identifier 114 may further determine the appropriate portions of the applicable sets. Put differently, layer identifier 114 may retrieve the appropriate shapefiles from the one or more applicable sets of shapefiles. The appropriate shapefiles may include polygons having one or more vertices with coordinates falling within the displayed portion of the reference map, lines having one or more vertices with coordinates falling within the displayed portion of the reference map, and/or vertices with coordinates falling within the displayed portion of the reference map. The appropriate shapefiles may be sent to the map server 111 as a response to the original request from the web browser 102.

According to one embodiment, the map server 111 may serve the appropriate shapefiles (retrieved by the layer identifier 114) and/or the reference shapefiles (retrieved by the map identifier 113) to the client system 100. The graphical composite assembler 107 may receive the shapefiles from the map server 111 while waiting to receive the customized data from the CHM web server 116. Upon receiving the customized data, the graphical composite assembler 107 may match the appropriate shapefiles (but not the reference shapefiles) with the tabular data received from the CHM web server 116. The image converter 106 may render a series of image tiles or raster files having the polygons, lines, and/or vertices included in the reference shapefiles and the appropriate shapefiles. The polygons, lines, and/or vertices of the appropriate shapefiles may be overlaid on the polygons, lines, and/or vertices of the reference shapefiles and be shaded according to the tabular data received from the CHM web server 116. The graphical image viewer 104 may assemble the rendered image tiles or raster files into an array according to assembly instructions produced by the image converter 106. The reference shapefiles may be rendered according to instructions received from the external server.

According to another embodiment, the map server 111 may convert the appropriate shapefiles and the reference shapefiles into raster files or image tiles. Each raster file or image tile may include polygons from the appropriate shapefiles, shaded according to the health data received from the CHM web server 116 and polygons from the reference shapefiles, shaded according to instructions received from the external server. To perform the conversion, the map server 111 may fill in or shade each polygon included in the appropriate shapefiles based on tabular data received from the CHM web server 116. Put differently, the shading of each polygon of the appropriate shapefiles may be based on data retrieved from CHM Web Server 116. As in the above embodiment, the shaded polygons of the appropriate shapefiles are overlaid on the polygons of the reference shapefiles during rendering. The map server 111 may deliver the raster files or image tiles (which may be images of the shaded polygons of the appropriate shapefiles overlaid onto the polygons of the reference shapefiles), instead of the appropriate shapefiles and the reference shapefiles, to the client system 100. The size of each polygon may based, at least in part, on a zoom level of the GUI 101.

In one embodiment, graphical image viewer 104 is configured to display graphical images in various graphical file formats. Dynamic display 103 of graphical image viewer 104 responds to inputs, such as macros, to dynamically change the display of responsive data on the web browser 102 in accordance with a user's commands. The dynamic display 103, for example, is configured to enable a user to move or pan the image displayed in web browser 102 and to zoom the image in or out. As the user moves, pans, and/or zooms, the dynamic display 103 may update or cause map identifier 113 to update the reference shapefiles being used to render the underlying reference map. As explained above, as the reference shapefiles used to display the underlying reference map are updated, the appropriate shapefiles may also be updated. As the user moves, pans, and/or zooms, the dynamic display 103 may update or cause map server 111 to serve (a) new shapefiles and/or (b) new raster files or image tiles. Web page renderer 105, or similar rendering engine, of web browser 102 ensures the image is properly displayed on the web page in the web browser 102. The web page renderer 105 combines various formats, including HTML and CSS. In one embodiment, the image is in HTML format and the navigation on the web page is performed via CSS.

The graphical composite assembler 107 may receive the data in an asynchronous manner. According to one embodiment, the graphical composite assembler 107 receives the appropriate shapefiles from the map server 111 and then instructs the image converter 106 to render the appropriate shapefiles according to health data later received from the CHM web server 116. According to another embodiment, the graphical composite assembler 107 receives the raster files or image tiles from map server 111 while waiting to receive customized data in tabular format from the CHM web server 116. Upon receiving the customized data in tabular format, the graphical composite assembler 107 may match the raster files or image tiles with the appropriate tabular data into a graphical composite. Image converter 106 may convert the assembled graphical composite into an image that can be viewed by the graphical image viewer 104.

Server system 110 is configured to receive entry by a user of server system 110 of a user ID 109 or other login credentials for ensuring that the user is provided access to only that information to which that user is allowed. Upon logging into the software hosted by server system 110, based upon the client identification and the login credentials of the user, server system 110 automatically modifies the menu of selectable options displayed on graphical user interface 101 of client system 100 for selection by the user. The user may then select from among one or more data analysis from the menu that are pre-customized for that user.

In operation, a user using a client device, such as a desktop computer, a laptop, a tablet, or a mobile device, connected to server system 110 would be provided by server system 110 with a login screen through which the user would enter the user's login credentials, such as login ID and password. Any variation of user authentication may be implemented by server system 110 as may be known in the art. Server system 110 is configured to provide a menu of data analyses from which the user may select. Such data analyses may include the preparation by server system 110 of a composite two-dimensional topographic map for display on the display of the user's device. Server system 110 may provide the user with various options or combination of elements from which the user may select that are associated with the requested data analysis.

Upon receipt of the user's request using web browser 102 connected to server system 110, in one embodiment, cloud-based map server 111 of server system 110 separately sends a request to CHM Web server 116. Map server 111 verifies the client ID 108 of the user's client computing device and sends the request to custom geographic data selection manager 112. Upon receipt of the request, geographic data selection manager 112 uses the map identifier 113 and/or the layer identifier 114 to select the appropriate shapefiles from the geo-spatial database 115 to render a map. Geographic data selection manager 112 sends the appropriate shapefiles to the map server 111. According to one embodiment, and as previously stated, the map server 111 serves the appropriate shapefiles to the client system 100. According to another embodiment, and as previously stated, the map server 111 serves the raster files or image tiles to web browser 102 of client system 100 for integration by web browser 102 into a map comprising a composite visualization of the requested data analysis.

Simultaneously, the CHM Web server 116 sends the request to the user security data assessor 117 to verify the user's group ID 109 and the data layer requested by the user. Upon verification that the user permissions are satisfied, the user request is received by the custom data selection manager 120. The custom data selection manager 120 queries the various databases 121,122,123,124 to retrieve the disparate data. Upon receipt of the disparate data components from the custom data selection manager 120, the CHM Web server 116 serves the data components to web browser 102 of client system 100 for integration by web browser 102 into a map comprising a composite visualization of the requested data analysis. In this way, server system 110 conducts the spatial and statistical analysis to match the user's request, and presents that data in a format that web browser 102 can interpret and assemble to graphically display the results.

Web browser 102 uses graphical composite assembler 107 to match the tabular data with (a) the shapefiles or (b) the raster files/image tiles to produce a composite graphic. The graphical composite assembler 107 may change the format of incoming data from the map server, which may be in the form of raster files, image files, and/or KML files. Image converter 106 converts the composite graphic into a Web page that can be viewed by graphical image viewer 104. Graphical image viewer 104 displays the Web page through graphical user interface 101, which may be any one of a number of displays associated with client system 100. Web browser 102 stores the layer information to prevent the need for server system 110 to retrieve the same layer if the user selects the same layer with new topographical elements.

Example: User Selection of Customized Data Analysis

In one example, a user wishes to conduct data analysis of a national account with employees across the 43,000 zip codes in the United States. In particular, the user desires to prioritize geographic areas where the account's employees have higher prevalence of hypertension in comparison to the prevalence of the general commercial population. Furthermore, the user seeks to limit the data analysis by controlling for social determinants of health. Finally, the user needs to identify local providers, community health centers, farmers markets, and social services that may be ideal partners to support population health management.

The user may log into the software hosted by server system 110 using a web browser 102 displayed on the client device of client system 100. The server system 110 presents a customized menu 130 on the web page displayed in the web browser 102 that is appropriate and/or customized for the user's user ID. The user may select the account and the hypertension prevalence layer. In addition, the user may select the layer that controls for the social determinants of health. Lastly, the user may select the local resources of interest.

The server system 110 automatically responds on the fly to the user's request by facilitating the collection and integration of data stored on disparate data sources, and preformats the results in a way that is interpretable and displayable by the user's web browser without any additional client-side software. The server system 110 pushes that formatted data to the user's web browser, which renders the account-specific information for hypertension prevalence in a composite visualization that allows the user to scan the map of the United States. The visualization renders an image of shape files for each zip code symbolized and/or represented in different colors that reflect zip codes with higher prevalence among the account population. Because the user controlled for social determinants of health, the visualization shades the shape files for the geographic areas controlled for by the user. The user may select or “click” on an area of the map and the shape file produces a pop-up display of the comparative data of the employee population to the general commercial population. The file size for the image could exceed 125 MB. By selecting providers and resources, the user can click on the displayed community assets to reveal the services provided by the local entity or hours of operation. Upon reviewing the services, the user can receive directions to the local entity by entering an address associated with the user's geographic location.

FIGS. 5-52 provide the results displayed in graphical user interface (GUI) 101 of Internet browser 102 of various exemplary searches on server system 110 that integrates community mapping data and social determinants of health data overlaid on a graphical map of the United States. In these embodiments, the data is configured for display by zip code. In other embodiments, the data may be displayed according to any other actual, artificial, or synthetic geographic or other boundary or grouping. For example, the data may be displayed by community, by city/town, by township, by county, by state, and by region, or any combination or subcombination of the foregoing.

Community mapping data may include data concerning medical condition prevalence, medical condition frontier, food access frontier, nutrition, population density centers, and health care providers, as shown by the references positioned on the bottom ribbon on FIG. 7 after selecting the tab 126 of graphical user interface (GUI) 101 of Internet browser 102.

Social determinants of health data may include data concerning minority population prevalence, race/ethnicity prevalence, linguistic isolation prevalence, prevalence of a foreign language as the primary language, level of education, per capita income, income distribution, unemployment prevalence, prevalence of population not in the labor force, poverty prevalence, prevalence of disabled people living in poverty, marital status, prevalence of female only householders, prevalence of no access to a vehicle, prevalence of the population enrolled in Supplemental Nutritional Assistance Program (SNAP), and family size, as shown by the references positioned on the bottom ribbon on FIG. 20 after selecting tab 127 of graphical user interface (GUI) 101 of Internet browser 102. One of ordinary skill would appreciate that other community mapping data and/or social determinants of health data may be utilized.

Condition prevalence in this disclosure refers to the proportion of the commercial population that presents in a reporting period, for example, the preceding 12-month period, with one inpatient claim of a particular health condition of interest or 2 outpatient claims of the condition of interest in the reporting period. For example, a user seeking to know the proportion of the commercial population that presents in a reporting period, for example, the preceding 12-month period, with one inpatient claim of a particular health condition of interest or 2 outpatient claims of the condition of interest in the reporting period may query system 110, as shown in FIGS. 8-9 .

In this embodiment, as shown in FIG. 8 , after entering a location, such as the name of a city, an address, or a zip code, into search box 128, a user may select the “hypertension prevalence” dropdown option 132 from among one or more selectable medical conditions in customized menu 130 to obtain the percentage of the population in the geographic location who is considered to have hypertension. The prevalence of this condition is presented to the user in graphical map image 134 where a different color or shading style is assigned to each zip code shown in the image 134 according to the prevalence of the item being searched. The geographic breadth of the image 134 may default to a particular zoom level, which zoom level may be adjustable by the user.

The image 134 is dynamically interactive with the user. Consequently, the user may select a particular color coded region corresponding to a particular zip code to obtain further statistics on the prevalence of the condition being searched. As shown in FIG. 9 , for example, the user selected the geographic tile 135 corresponding to zip code “36108” (item 137), after which system 110 responds by displaying text box 136 with detailed statistical data corresponding to that zip code and for the selected health condition, which in this example, is hypertension prevalence, including community characteristics for the general population in that zip code. Legend 138 may be configured to dynamically update with information corresponding to the zoom level of image 134.

Condition frontier in this disclosure refers to, for any given medical condition selected above, the observed-to-expected ratio of the commercial population compared to the general population. Populations in underperforming zip codes may be identified relative to nationwide zip codes with these characteristics. Social Determinants of Health (SDOH) include cultural factors (e.g., race/ethnicity and language), economic factors (e.g., per capita income), educational factors (e.g., completion of primary education) and social factors (e.g., female head of household and access to vehicle).

FIGS. 10 and 11 take the foregoing example a step further by identifying one or more social factors that may explain the prevalence of hypertension in the selected location. For example, once hypertension prevalence displayed in the user's browser, the user may select “Hypertension Frontier” in the dropdown option 142 from among one or more selectable options in customized menu 130 to identify underperforming zip codes relative to nationwide zip codes with similar community characteristics. The prevalence of hypertension (or any condition that is previously selected) is presented to the user in graphical map image 144 where a different color or shading style is assigned to each zip code shown in the image 144 according to the prevalence of the item being searched. The geographic breadth of the image 144 may default to a particular zoom level, which zoom level may be adjustable by the user.

The image 144 is dynamically interactive with the user. Consequently, the user may select a particular color coded region corresponding to a particular zip code to obtain further statistics on the item being searched (in this example, the hypertension frontier). As shown in FIG. 11 , for example, the user selected the geographic tile 145 corresponding to zip code “36117” (item 147), after which system 110 responds by displaying text box 146 with detailed statistical data corresponding to that zip code and for the selected health condition, which in this example, is hypertension prevalence and the hypertension observed-to-expected ratio (O/E) associated with that condition for that zip code, including community characteristics for the general population in that zip code. Legend 148 may be configured to dynamically update with information corresponding to the zoom level of image 144.

Food access frontier in this disclosure refers to the availability of food options and access thereof, by zip code. The food access frontier comparison considers relatively low areas of healthy food options (e.g., “food deserts”) and high areas of unhealthy food options (e.g., “food swamps”). The methodology employed by server system 110 may control for median household income and commuting patterns, which may be described as part of the economic sphere of daily activity. The calculated results may be arrayed by deciles, as shown in FIGS. 12-13 .

For example, after entering a location, such as the name of a city, an address, or a zip code, into search box 128, a user may select the “food access frontier” dropdown option 152 from among one or more selectable nutritional options in customized menu 130 to obtain the availability by the population to different food options in that geographic location.

As discussed above, the results of the food access frontier search for the particular geographic location entered into search box 128 are presented to the user in graphical map image 154 where a different color or shading style is assigned to each zip code shown in the image 154 according to the prevalence of the item being searched. The geographic breadth of the image 154 may default to a particular zoom level, which zoom level may be adjustable by the user.

As discussed above, the image 154 is dynamically interactive with the user. Consequently, the user may select a particular color coded region corresponding to a particular zip code to obtain further statistics on the food access frontier. As shown in FIG. 13 , for example, the user selected the geographic tile 155 corresponding to zip code “36117” (item 157), after which system 110 responds by displaying text box 156 with detailed statistical data corresponding to that zip code and for the selected nutritional dropdown item. In this example, the food access frontier (in deciles), average distance to the nearest grocer, food options within the daily commuting sphere, number of food options, and median household income may provide an indication of the environmental and socioeconomic impact on health of the population represented by the selected geographic location. Legend 158 may be configured to dynamically update with information corresponding to the zoom level of image 154.

The geographic breadth of the image 204 may default to a particular zoom level, which zoom level may be adjustable by the user.

As discussed above, the image 204 is dynamically interactive with the user. Consequently, the user may select a particular color coded region corresponding to a particular zip code to obtain further statistics on race/ethnicity for the selected geographic location. As shown in FIG. 24 , for example, the user selected the geographic tile 205 corresponding to zip code “60636” (item 207), after which system 110 responds by displaying text box 206 with detailed statistical data corresponding to that zip code and for the selected cultural factors dropdown item. Legend 208 may be configured to dynamically update with information corresponding to the zoom level of image 204.

Similarly, FIGS. 25-26 show representative cultural factor data associated with linguistics isolation, which is defined in this embodiment as referring to the prevalence of families and/or the proportion of the population in the selected geographic location that have no one over the age of 14 having English as the primary language. FIGS. 27-28 show representative cultural factor data associated with speaking primarily a foreign language, which is defined in this embodiment as referring to the identities and prevalence of the primary or preferred foreign languages spoken within the selected geographic location. Each of these cultural factor options for a selected geographic location may be displayed in the same way as discussed above.

FIGS. 29-30 show representative educational factor data associated with the proportion of people having a selected level of education in a selected geographic location. For example, a user using system 110 may identify zip codes having a higher proportion of people that have completed only primary education, along with other socioeconomic statistics about the population.

FIGS. 31-32 show representative economic factor data associated with the per capita income of people in a selected geographic location. FIGS. 33-34 show another example of economic factor data reflecting the distribution of income in the selected geographic location. System 110 may use a zip code Gini coefficient, which is a measure of inequality of a distribution (in this example, wealth) defined as a ratio with values between 0 and 1. The numerator is the area between the Lorenz curve of the distribution and the uniform distribution line. The denominator is the area under the uniform distribution line. System 110 may display a pop-up window representing an income distribution layer, which may contains additional detailed information for the categorical distribution of income-to-poverty ratio. In one embodiment, the income-to-poverty ratio is a family's or person's income divided by their poverty threshold, as defined by the US Census Bureau. The income-to-poverty ratio categories shown in FIG. 34 represent variations of the poverty level within a zip code or geographic location. Ratios below 1.00 (below 100% of poverty) are below the official poverty definition provided by the US Census Bureau, while ratios of 1.00 or greater (100% of poverty or greater) indicate income above the poverty level. Ratios below 0.50 (50% of poverty) may be described as “severe poverty”, while those with ratios at/or above 1.00 but less than 1.25 may be described as “near poverty”.

FIGS. 35-36 show representative economic factor data associated with the rate of unemployment in a selected geographic location. FIGS. 37-38 show representative economic factor data associated with the prevalence and/or proportion of people not in the labor force in a selected geographic location. FIGS. 39-40 show representative economic factor data associated with the prevalence of families living in poverty in a selected geographic location. In one embodiment, poverty is defined by the US Census Bureau as money income, before taxes, relative to family size and composition and do not vary geographically. FIGS. 41-42 show representative economic factor data associated with the prevalence and/or proportion of disabled people who are living in poverty in a selected geographic location. This layer may identify the relationship between disability and poverty and the impact of the foregoing on health.

FIGS. 43-44 show representative social factor data associated with the prevalence and/or proportion of people of a specific marital status, such as divorced, separated, widowed, and married, in a selected geographic location. FIGS. 45-46 show representative social factor data associated with the prevalence and/or proportion of families having a female as the householder in a selected geographic location. In one embodiment, a family household contains at least 2 persons—the householder and at least one other person related to the householder by birth, marriage, or adoption. FIG. 46 shows representative detailed social factor data for female as the householder together with the distribution by race/ethnic groups. FIGS. 47-48 show representative social factor data associated with the prevalence and/or proportion of people without access to a vehicle in a selected geographic location. FIGS. 49-50 show representative economic factor data associated with the proportion of the population enrolled in Supplemental Nutritional Assistance Program (SNAP) in a selected geographic location. FIGS. 51-52 show representative social factor data associated with the prevalence and/or proportion of families exceeding the average family size in a selected geographic location.
